Question

5x+2y=13
2x+6y+26
what is the answer to the question

Answer 1

Explanation:

5x+2y=13

2x+6y=26

`5x = 13 - 2y \\ x = (13 - 2y)/(5)`

`2( (13 - 2y)/(5) ) + 6y = 26`

`(26)/(5) - (4y)/(5) + 6y = 26`

`6y - (4y)/(5) = 26 - (26)/(5) \\`

`5.2y = 20.8 \\ y = 4 \\ x = (13 - 2 * 4)/(5) = (13 - 8)/(5) \\ x = 1`
